Purpose or Objective

The present consensus was developed by spanish radiation oncologists on behalf of the subgroup GINECOR of the Spanish Society of Radiation Oncology, to provide a current review of technical aspects of radiation treatment of vulvar cancer

Material and Methods

Prior to the discussion of the statements, it was performed an extensive analysis of current medical literature from peer-reviewed journal to define evidence-based treatment options. A 2-round web-based modified Delphi study was conducted to reach a consensus on the appropriateness of the different therapeutic options in each clinical setting. Based on the results of the first round, 15 key questions of interest were proposed regarding the following items: Technical aspects of external beam radiotherapy and brachytherapy in each of the three clinical scenarios, adjuvant treatment of vulvar cancer, radiation treatment of locally advanced vulvar carcinoma; and locoregional recurrences.

Results

Recommendations based on second round questionnaire are listed in table 1. Table 2 resumes the recommendations on external beam radiotherapy and brachytherapy in both clinical scenario, adjuvant and unresectable vulvar carcinoma. The approach to a recurrence of vulvar carcinoma must be individualized for each patient in different clinical scenarios

Conclusion

In those aspects of vulvar, cancer were evidence is not definitive, expert panel consensus may help in clinical decision-making.
